FROG PET A HOST!

We go to great pains to get pets from wherever not caring the costs. But think before you import frogs. They could be carriers of a parasite called Chytrid fungus resposible for the death of amphibians in many parts of the world. For more read

  • Homo sapiens is a cruel and selfish species... and we are supposed to be the only species with a conscience??? This has always intrigued me.

  • Vincent that was a really interesting topic you brought up - that is why we are also presenting a course on Invasion Biology, and I will raise this article with those doing the course.

  • Hi Vincent
    If you have some more information on this I would like to read it some time please. Yes I don't think many people will think that frogs are carrying parasites, especially not if it is a fungus!

  • Hi Vincent

    You are correct 110%! One of my main arguments is the potential for parasitic invasion of our natural fauna, particularly the fishes, as a result of the uncontrolled (quarantine) importation of related species. Do a Google search for Gyrodactylus salaris as another good economically important and historically significant parasite.

  • Why not just inject the frog with Dr. Manto Tshabala's unique anti parasitic garlic anitidote?
    Have you thought about that?

    I bet you didn't!



    Ps: Just a joke...Peeps

  • The aquaculture industry has the same problems. The native or endemic species did not evolve the necessary defense mechanisms to fight off the foreign parasites, killing indigenous species. People obviously do not realise the seriousness of bringing exotic species into the country.

  • i thought animals goes through a medical check-up before they are taken to another country. i also heard that the was an animal which eats people which was also brought to S.A it is now at Pretoria zoo

  • Lethabo, you are correct, there is legislation which governs the importation of organisms into South Africa, however, as with many things in this country, there are not enough trained people to do the job correctly and enforce the legistlation. Through general ignorance, many invasive and cryptic species enter our country with the potential to threaten our ingigenous fauna. Parasites of fishes for example can be extremely invasive and yet the Agricultural Pests Act states that the responsibility of quarantining imported fishes, falls on the importer and not the state. How many importers can afford to run quarantine prophylaxes through 30-day regiments, and how many of them are qualified to make microscopic definitive diagnoses? Legislation needs to be re-written!

    Bentley, I likes you comment, but hwat is eally funny is that extract of garlic is actually being looked at as a possible treatment against the ciliated protozoan ectoparasite Cryptocaryon irritans. Maybe our minister has her eye on the aquaculture industry after all!

    Cheers
